Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a housing structure for a telephone that is constructed by combining a back cover, a mouthpiece, and a case having an earpiece.

[Conventional technology]

Conventionally, this type of telephone housing structure has a fourth
As shown in the figure, the case 20 is constructed by combining a case 20 having a mouthpiece 21 and a mouthpiece 22 at the front and rear in the longitudinal direction, and a cover 14 that forms a pair with the case 20 and forms the back side. The mating structure of the cover and case is
Fitting protrusions 15 and 16 are provided on the inside of both longitudinal ends of the cover 14 so as to face each other, and the case 2
On the 0 side, there is a recess 2 that accommodates the fitting protrusions 15 and 16.
3 and 24, and one of the fitting protrusions 15 and 16, for example, the fitting protrusion 15, is made longer and the recess 2 is made longer.
3 is formed deeply, and this is fitted first. Using this fitting part as a fulcrum, the cover 14 and the other end of the case 20 are aligned, and the fitting protrusion 16 is fitted into the recess 24 by elastic deformation of the cover 14. and fasten the screw 19 nearby.
It is structured to do this. At this time, since there is a distance between the screw fixing position and the fitting part of the transmitting end, outward fitting claws 25 are provided on both sides of the case as shown in FIG. Cover 14 or case 2
The fitting pawl 25 is fitted into the fitting recess 17 provided on the inner surface of the cover by elastic deformation in the width direction of the cover 14, thereby ensuring secure fastening of the cover 14 and the case 20.

[Problem that the invention attempts to solve]

In the conventional telephone housing structure described above, both the longitudinal rear end and the fitting parts on both sides are elastically deformed by the cover, etc., so when removing the cover 14 for maintenance etc. , the fitting must be released again by elastic deformation, making it extremely difficult to remove. In addition, as described above, the depth of the fitting claws 25 on the side surface cannot be made deep considering the attachment and detachment of the cover 14, and the shape of the ribs on the mating end surfaces of the cover 14 and the case 20 is as shown in FIG. As shown in FIG. 2, the cover 14 is structured to cover the outside of the rising rib 27 of the case 20 so that the cover 14 can be elastically deformed. Therefore, if the cover 14 receives an outward force due to an impact such as a fall,
If the fitting claw 25 comes off or the cover 14,
Even if the cover 14 is slightly deformed in the direction of opening outward and the case 20 is slightly deformed in the direction of contracting inward during molding of the case 20, the fitting of the side fitting claws 25 will not become loose or come off. For telephones etc. that are easy to install and have high density mounting, cover 1 is used.
4. There is a disadvantage in that appearance defects such as gaps between the mating surfaces of the side surfaces of the case 20 are likely to occur.

[Means for solving problems]

The telephone housing structure of the present invention is such that, in a telephone housing in which a back side cover is combined with a case having a mouthpiece and an earpiece, an inward fitting is provided inside the tip of the cover corresponding to the earpiece side of the telephone. A mating protrusion, a recess provided on the case side so that the mating protrusion fits into the mating protrusion, a screw fastening part at the rear end of the mouthpiece side as a means for fastening the case and the cover, and a screw part on both longitudinal sides. , provided on the cover side,
Alignment of an L-shaped fitting claw with an opening in the direction of the mouthpiece, an L-shaped fitting recess on the case side that is provided so that the fitting claw fits into it by sliding the cover, and the cover of the case. It consists of grooves formed on the mating end faces in the longitudinal direction of the cover so as to sandwich the rising ribs provided on the end faces.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Fig. 1 is an exploded perspective view of one embodiment of the present invention, Fig. 2 is a sectional view showing the side fitting part in the combined state, and Fig. 3 is the rib shape of the mating end surfaces of the cover and case. FIG. In the cover 1 on the back side constituting the phone housing, a fitting protrusion 2 having a predetermined length facing inward is provided inside the tip that meets the earpiece 7 side of the case 6, and
The case 6 is provided with a recess 9 having a depth to which the fitting protrusion 2 fits. On both longitudinal sides of the cover 1, there are L-shaped fitting claws 3 that protrude toward the inner surface of the case.
An L-shaped fitting recess 10 is provided on both longitudinal sides of the case 6 to form an inverted L-shaped receiving part and allow the fitting claw 3 to be fitted from the earpiece 7 direction. There is. A rising rib 13 is provided on the end surface of the case 6 where the cover 1 and the case 6 meet.
A groove 12 is formed approximately in the center of the wall thickness of the mating end face in the longitudinal direction of the cover 1 so that a rib 13 is fitted therein.

Insert the cover 1 into the earpiece 8 from the earpiece 7 side of the case 6.
When it is slid toward the side, each fitting protrusion and fitting claw fit together. After this fitting, the cover 1 and the case 6 are fastened together by fixing near the mouthpiece with screws 5 or the like. In this case, the mating depth of the side mating claws 3 in the housing width direction does not affect the internal mounting because the mating of the claws is not by elastic deformation as in the past, but by a sliding method. It is possible to deepen the range. Also, the rising rib 1 on the mating end surface
3 fits into the groove 12, it is possible to prevent the cover 1 from falling inward due to external force and the case 6 from opening outward, thereby ensuring secure fastening by the side fitting claws 3. be able to.

[Effect of idea]

As explained above, in the present invention, the cover and the case that constitute the telephone housing are fitted and fastened together by the fitting protrusion on the earpiece side and the fitting claw on the side surface by sliding of the cover and the case. Further, the rising ribs on the mating end surface of the case fit into the grooves on the longitudinal end surface of the cover. Therefore, it is possible to reliably prevent the side surfaces from becoming disengaged due to deflection of the cover and case due to external force or the like, and there will be no gap caused by the side openings. In addition, during normal use, the cover does not easily come off, and in the case of maintenance, etc., it can be removed simply by releasing the screws and sliding the cover, making it easy to attach and detach.
